Add a test for "git branch" to cover the case where .git/refs is symlinked. To check availability, refs_verify_refname_available() will run refs_read_raw_ref() on each prefix, leading to a read() from .git/refs (which is a directory).
It would probably be more robust to re-issue the lstat() as a normal stat(), in which case, we would fall back to the directory case, but for now let's just test for the existing behavior as-is. This test covers a regression in a commit that only ever made it to "next", see [1].
